Narrow Wood Band (WB) blades
These blades are for cutting hard or soft wood.  These are thin gauge blades with minimum material wastage.  They are made from pre-tempered high carbon steel with uniform hardness of RC 44-46.  We stock WB blades for applications where TK blades are either not available in narrow widths, or too thick for bandsaws with smaller wheels.

Hard Edge Flex Back (FB) blades and Thin Kerf Hard Edge Flex Back (TK or TKO) blades
These blades are for cutting hard or soft wood, plastic and non-ferrous (soft) metal. These are heavier duty, more durable blades made from high carbon steel with tooth hardness RC 62-63 and back hardness RC 28-32. The thinner gauge TK/TKO blades offer reduced material wastage and can be used on most smaller bandsaws.  FB and TK/TKO blades last 3 to 5 times longer than WB blades.

Bi-Metal (BM) blades
These blades are for cutting harder metals including alloy steel.  They are also a good choice for cutting exotic hard wood or wood with imbedded hard material.  They have a high speed molybdenum matrix cutting edge, electron beam welded to a low alloy, shock resistant back.  Bi-Metal blades provide faster cutting rates and increased life (up to 10 times longer life than FB blades). They have excellent toughness, shock and abrasion resistance.  CAUTION - Blade speed must be between 50 and 300 lineal feet per minute to cut mild steel or harder metals.  The blade will not last on these materials at high blade speed.  To determine blade speed in lineal feet per minute use formula:  rpm x wheel diameter (inches) x 0.26.  Use with variable speed drive to achieve this.

Selecting blade width
For cut-off sawing the blade should be as wide as the machine will allow.  The wider the blade, the straighter the cut.  Faster feed can also be achieved.  For contour sawing the blade should be as wide as the machine will allow, but still narrow enough so it can cut the desired radius:
